About Holtara

What we stand for:

Our current economic system has brought unprecedented levels of welfare and prosperity. Yet, it is clear that the ways we produce, consume, and finance will need to change. We believe that investors play a crucial role in this transition: first, by better understanding the impact of their investments on climate change, ecosystems, and society; and second, by actively challenging their investments to reduce negative impacts while capturing the opportunities the sustainability transition provides.

What we do:

Holtara is leading the way in building effective ESG & sustainability programs, combining expert advisory and technology services across the investment lifecycle. We support investors, asset managers, and businesses in translating sustainability ambition into measurable action, helping them create real impact today for a more sustainable tomorrow.
Environmental, Social, and Governance (ESG) factors, while non-financial, can have a material impact on a company’s long-term risk profile and financial performance. Companies that effectively apply ESG practices tend to be more responsible, less risky, and better positioned for long-term success.

As investors increasingly recognise the importance of ESG, they work with us to measure, analyse, and improve the sustainability performance of their investments. Together with companies across a wide range of geographies and industries, we assess current ESG performance, define clear improvement priorities, and support implementation over time. By working directly with company management — supported by committed investors — we are able to drive real, measurable impact and track progress year after year.

About the role

As an Intern in our Advisory team in Amsterdam, you will work closely with senior consultants on active client engagements in sustainability. You may contribute to projects such as carbon footprint assessments, ESG due diligence reports, regulatory and sustainability disclosures, and client workshops.

This is a paid, full-time internship position, designed for students or recent graduates who are passionate about sustainability and want to accelerate their careers by developing practical consulting skills. Learning takes place primarily through hands-on participation in client projects, with close guidance from experienced colleagues. You will develop yourself rapidly in a dynamic and fast-paced setting, take on meaningful responsibilities, and contribute to creating sustainable impact at scale.

What you will be working on

• Analyse and solve. Conduct desk research, GHG footprint calculations, social impact assessments, materiality analyses, and policy benchmarking; translate data into actionable insights.
• Craft deliverables. Build models, slides, dashboards, and reports that translate complex sustainability topics into clear narratives for clients and investors.
• Support client engagement. Help facilitate client meetings, workshops, strategic sessions, and trainings.
• Research. Stay up to date on industry trends, regulatory developments, voluntary standards, and best practices. Summarize key insights for the team and build your knowledge in sustainability topics.
